Study Notes
Voyage of the Beagle
- The HMS Beagle, a British ship, set sail in 1831 with Charles Darwin on board as the ship's naturalist.
- The voyage lasted from 1831 to 1836 and covered over 40,000 miles.
Observations on the Galapagos Islands
- Darwin spent five weeks on the Galapagos Islands in 1835.
- He collected numerous specimens, including finches, tortoises, and iguanas.
- He observed that:
- Finches had distinct beak shapes and sizes, correlating with their diets.
- Tortoises had distinct shell shapes, correlating with their habitats.
- Iguanas had distinct scales, correlating with their habitats.
Observations on Fossil Record
- Darwin discovered fossils of extinct species in South America, including giant sloths and armadillos.
- He observed that:
- Fossils of extinct species were often found in the same geological layers as living species.
- Fossil species showed gradual changes over time, with more recent fossils resembling living species.
Observations on Variation and Adaptation
- Darwin observed variation within species, including:
- Different species of finches on the Galapagos Islands.
- Different breeds of dogs, exhibiting diverse characteristics.
- He noted that:
- Variation within species can lead to adaptation to specific environments.
- Adaptation can lead to the formation of new species.
Implications of Observations
- Darwin's observations led him to question the fixity of species and the concept of special creation.
- He began to formulate his theory of evolution through natural selection.
